The Bresser Messier Newtonian telescopes have established themselves as reliable workhorses for astrophotography in recent years. With the new Messier NT-203s/800 with Hexafoc, we can now present a new generation of these devices. With their fast focal ratio of 203mm (8″) f/3.9, the Photo Newtonians with parabolic primary mirror allow deeper images with the same exposure time. The large 85 mm secondary mirror ensures optimum illumination of the image field. The high-quality 2.5″ Hexafoc focuser ensures problem- and vignetting-free photography, tube clamps with 44mm universal dovetail bar and carrying handle with mounting option for a camera as well as an excellent bright viewfinder with crosshairs round off the picture of these high-quality devices.
Mount, tripod & handbox with computer.
This German mount is equipped with tracking motors in both axes, which can accurately track and position astronomical objects. The handbox with GoTo function controls the mount precisely and reliably. Precision gears in both axles allow operation with a minimum of gear backlash at all of the nine possible speeds. The battery pack (12 V) is conveniently attached to the storage table and holds 8 “D” size batteries. The mount comes with a solid tubular steel tripod with high stability and can be loaded with optical tubes weighing up to 13 kg. The GoTo control system makes sky observation easy at the touch of a button!
